关键词：雨刮器；间歇电路控制；虚拟设计； ADAMS；Pro/Eper is a small part of automotive but can not be ignored. It can polish the windscreen so that the driver's attention will be more clearly. Its function is to wash the glass to obtain a clear field of vision and ensure the traffic safety. Some countries have had the state of wiper technology projects included into the annual inspection of vehicles. My design requirements are to design the size of the wiper parts in the car, solving the linked scan area, motor selection, circuit analysis, motion analysis using ADAMS software, trajectory and speed of access to and using Pro / E draw three-dimensional model. The use of three-dimensional modeling software, Pro/E, and dynamic simulation software, ADAMS, to establish a model of the wiper, simulate the full motion, analyze the movement curves of wiper, make a further design to the wiper , increase the scratch brush area further , and provide a theoretical reference for the actual production.

要
汽车雨刮器， 是一个很小却又不容忽视的汽车部件， 它能擦亮汽车的挡风玻璃， 使司机的视线更加清晰。其功能是将玻璃上的雨水、尘埃、泥污刮净，以获得清晰 的视野，保证行车安全。有的国家已将雨刮器的技术状态列入车辆年检项目。 本设计要求进行轿车雨刮器部件尺寸的设计，求解刮扫面积，电机选型，电路 分析，利用 ADAMS软件进行运动分析，获得运动的轨迹和速度，并用 Pro/E 绘出三 维模型。 运用三维建模软件 Pro/E 与动力学仿真软件 ADAMS 建立雨刮器模型，并进行 运动仿真，分析雨刮器的运动曲线，对雨刮器做进一步的设计，力求使刮刷区域进 一步增大，为生产实际提供理论参考。
